Complete the food critic's harsh (but funny) review of a new restaurant.

I thought the soup was terrible, but the main course was actually ______ than the appetizer!

The correct answer is worse.

The adjective "bad" has an irregular comparative form. We do not add "-er" or use "more"; instead, "bad" changes completely to worse when comparing two things. "Worst" is the superlative form used for three or more things.
